| Manmade objects left orbiting Earth - such as a satellite parts - are described as space junk. There are tens of thousands of pieces of space junk bigger than 10cm (4in) in orbit around the Earth and they can burn up like meteors as they enter the atmosphere. | Manmade objects left orbiting Earth - such as a satellite parts - are described as space junk.

| The UK Meteor Network said it was "investigating to ascertain what the object was, meteor or space debris" but could not identify the cause of the "slow-moving meteor", which was seen burning through the atmosphere for about 20 seconds. | |
| Kevin Morgan, from UK Meteor Network, told BBC Radio's Good Morning Scotland said the speed it was travelling at could indicate that it was space junk. | |

| "At this point we cannot find any known space junk or satellite de-orbit that could account for this fireball. We are looking at the data again." | |
| There have been nearly 800 reports of the fireball that was seen over UK last night. The preliminary trajectory has been calculated by the IMO and indicates that the object, which we now believe to be space debris, would have landed in the Atlantic south of the Hebrides. pic.twitter.com/skSvl0YH5Y | |
| The International Meteor Organization had almost 800 witness reports from across the UK and Ireland. The majority were from Central Scotland but there were also sightings from the Black Isle and Kinnaber in the east, near Montrose and as far south as London. | The International Meteor Organization had almost 800 witness reports from across the UK and Ireland.
